Description

Technical Field

[0001] The present application relates to the technical field of concrete processing, and in particular to a device for recovering waste concrete slurry. Background Art

[0002] Waste slurry treatment is a critical and complex process in the production and operation of concrete mixing plants. Waste slurry primarily consists of a mixture of cement slurry, aggregates (such as sand and gravel), admixtures, and impurities generated during the washing of mixers and transport vehicles. This waste slurry not only contains a large amount of recyclable resources, such as sand and gravel, but also often contains high concentrations of alkaline substances in the wastewater. Direct discharge of this waste slurry would cause serious environmental pollution. Therefore, waste slurry recycling has become a key measure for environmental protection and resource conservation in concrete mixing plants.

[0003] An existing patent (publication number: CN215310628U) discloses a waste slurry recycling device for a concrete mixing plant, which relates to the field of concrete processing technology. The device includes a main body seat, a main body box mounted on the top of the main body seat, an auxiliary box mounted on the top of the main body seat, located inside the main body box, a feed chute mounted on the top of the main body box, two discharge guide plates on both sides of the main body box, and a first discharge guide plate on the outer wall of the main body box. The utility model is provided with a feed box, a screening net, and a main body box. During use, wastewater and waste residue are poured into the main body box through the feed chute. The wastewater and waste residue poured into the main body box are filtered through the screening net. Smaller waste residue particles and wastewater are filtered through the screening net and flow into the auxiliary box. Some larger waste residue particles are discharged outward through the second discharge guide plate connected to the auxiliary box for further treatment, thereby separating the waste residue and improving the efficiency of waste residue treatment.

[0004] However, since the waste slurry contains a large amount of solid particles and impurities, these particles easily accumulate and clog the mesh when passing through the filter, resulting in a decrease in filtration efficiency or even a complete loss of filtration function. The filter blockage not only affects the processing speed and effect of the waste slurry, but may also cause damage to the equipment and increase maintenance costs. Utility Model Content

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a waste concrete slurry recovery device, comprising a collection box, wherein the top of the collection box is fixedly connected to two support seats, filter cartridges are fixedly connected to the interiors of the two support seats, the middle and right ends of the filter cartridges are provided with filter holes, a push shaft is rotatably connected between the left and right inner side walls of the filter cartridge, and an auger blade is fixedly connected to the outer surface of the push shaft;

[0007] The right end of the filter cartridge is fixedly connected to a feed hopper, the left end of the filter cartridge is fixedly connected to a support plate, a knocking shaft is rotatably connected between the support plate and the feed hopper, a plurality of connecting ropes are fixedly connected to the outer surface of the knocking shaft, and one end of each connecting rope is fixedly connected to a vibration ball.

[0008] Through the above scheme, through the combined structure of the knocking shaft and the vibrating ball, when the filter hole is blocked, the motor is reversed to drive the push shaft to rotate, and at the same time, the knocking shaft is rotated through the belt drive and the one-way bearing, so that the vibrating ball can continuously knock the filter cartridge, effectively preventing the filter hole from being blocked, ensuring that the waste slurry can pass smoothly, and significantly improving the filtration efficiency and stability. Combined with the structure of the auger and the filter cartridge, the solid impurities such as sand and gravel in the waste slurry can not only be effectively filtered under the pushing action of the auger, but also be quickly pushed to the discharge trough for discharge, reducing the residence time of impurities in the device, thereby improving the overall processing efficiency. The partition plate arranged in the collection box effectively separates the filtered wastewater and solid impurities, which is convenient for subsequent recycling and treatment.

[0009] Furthermore, a partition plate is fixedly connected to the inner side wall of the collection box.

[0010] Through the above solution, the purpose of solid-liquid separation can be achieved by setting the partition plate.

[0011] Furthermore, a discharge trough is provided at the left end of the filter cylinder.

[0012] Through the above solution and the provision of the discharge chute, the purpose of solid impurities falling out can be achieved.

[0013] Furthermore, a motor is fixedly mounted on the right side of the filter cartridge, and an output end of the motor is fixedly connected to the push shaft.

[0014] Through the above solution, the motor is set to provide power for the rotation of the push shaft.

[0015] Furthermore, two symmetrically arranged guard plates are fixedly connected to the top of the collection box.

[0016] Through the above solution and the provision of the guard plate, the purpose of shielding the filter cartridge can be achieved.

[0017] Furthermore, four moving wheels arranged in a matrix are fixedly mounted on the bottom of the collection box.

[0018] Through the above solution and the provision of moving wheels, the overall movement can be facilitated.

[0019] Furthermore, the right side of the collection box is fixedly connected to a drain pipe, and a valve is installed at the right end of the drain pipe.

[0020] Through the above solution and the provision of the liquid discharge pipe, it is convenient for the user to discharge liquid.

[0021] Furthermore, the left end of the pushing shaft is fixedly connected to a first pulley, the outer surface of the knocking shaft is rotatably connected to a second pulley via a one-way bearing, and the two pulleys are connected via a belt transmission.

[0022] Through the above solution and the provision of the one-way bearing, it is possible to achieve the purpose that when the motor rotates reversely, the knocking shaft rotates accordingly, and when the motor rotates forward, the knocking shaft does not rotate.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The device for recovering waste concrete slurry adopts the combined structure of a striking shaft and a vibrating ball. When the filter hole is clogged, the motor is used to reversely drive the pushing shaft to rotate. At the same time, the striking shaft is rotated through a belt drive and a one-way bearing, so that the vibrating ball can continuously strike the filter cartridge, effectively preventing the filter hole from being clogged, ensuring that the waste slurry can pass smoothly, and significantly improving the filtration efficiency and stability. Combined with the structure of the auger piece and the filter cartridge, solid impurities such as sand and gravel in the waste slurry can not only be effectively filtered under the pushing action of the auger piece, but also be quickly pushed to the discharge trough for discharge, reducing the residence time of impurities in the device, thereby improving the overall processing efficiency. The partition plate arranged in the collection box effectively separates the filtered wastewater and solid impurities, facilitating their subsequent separate recycling and processing.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] See also Figure 1 、 Figure 2 and Figure 4 In this embodiment, a waste concrete slurry recovery device includes a collection box 1. Four moving wheels 16 arranged in a matrix are fixedly installed at the bottom of the collection box 1. The setting of the moving wheels 16 can facilitate the movement of the whole. The inner wall of the collection box 1 is fixedly connected with a partition plate 12. The setting of the partition plate 12 can achieve the purpose of solid-liquid separation. The top of the collection box 1 is fixedly connected to two support seats 2. The inside of the two support seats 2 is fixedly connected with a filter cartridge 3. The top of the collection box 1 is fixedly connected with two symmetrically arranged guard plates 15. The setting of the guard plates 15 can achieve the purpose of shielding the filter cartridge 3. The right side of the collection box 1 is fixedly connected with a drain pipe 17. The right end of the drain pipe 17 is installed with a valve 18. The setting of the drain pipe 17 can facilitate the user to discharge the liquid.

[0033] See also Figure 1 、 Figure 2 and Figure 3 A discharge trough 13 is provided at the left end of the filter cartridge 3. The setting of the discharge trough 13 can achieve the purpose of solid impurities falling out. Filter holes 4 are provided at the middle and right ends of the filter cartridge 3. A push shaft 5 is rotatably connected between the left and right inner walls of the filter cartridge 3. The outer surface of the push shaft 5 is fixedly connected to a screw piece 6. Through the setting of the screw piece 6 and the filter cartridge 3, the purpose of filtering sand and gravel can be achieved, and the sand and gravel can be pushed to move.

[0034] See also Figure 1 、 Figure 2 and Figure 3The left end of the filter drum 3 is fixedly connected to the first pulley 19, and the outer surface of the knocking shaft 9 is fixedly connected to the second pulley 20 through a one-way bearing. The two pulleys are connected by a belt drive. Through the setting of the one-way bearing, it can be achieved that when the motor 14 is reversed, the knocking shaft 9 follows the rotation, and when the motor 14 rotates forward, the knocking shaft 9 does not rotate.

[0035] A waste concrete slurry recovery device in this embodiment uses a combined structure of a knocking shaft 9 and a vibrating ball 11. When the filter hole 4 is blocked, the motor 14 is used to reversely drive the push shaft 5 to rotate. At the same time, the knocking shaft 9 is rotated through belt transmission and a one-way bearing, so that the vibrating ball 11 can continuously knock the filter cartridge 3, effectively preventing the filter hole 4 from being blocked, ensuring that the waste slurry can pass smoothly, and significantly improving the filtration efficiency and stability. Combined with the structure of the auger piece 6 and the filter cartridge 3, solid impurities such as sand and gravel in the waste slurry can not only be effectively filtered under the pushing action of the auger piece 6, but can also be quickly pushed to the discharge trough 13 for discharge, reducing the residence time of impurities in the device, thereby improving the overall processing efficiency. The partition plate 12 provided in the collection box 1 effectively separates the filtered wastewater and solid impurities, facilitating subsequent separate recycling and treatment.

[0036] The working principle of the above embodiment is as follows: first, the waste slurry enters the interior of the filter cartridge 3 through the feed hopper 7. At this time, the solid particles in the waste slurry, such as sand and gravel, impurities and wastewater begin to be initially separated. The wastewater and smaller solid particles will pass through the filter holes 4 and enter the collection box 1 area below the filter cartridge 3, while the larger solid particles will be blocked by the filter cartridge 3.

[0037] Next, the motor 14 starts, driving the push shaft 5 to rotate, and the auger pieces 6 fixed on the push shaft 5 rotate accordingly. These auger pieces 6 push the solid particles, mainly sand and gravel, in the filter cartridge 3 to the left like a spiral bulldozer. As the auger pieces 6 continue to rotate, the solid particles are gradually pushed toward the discharge trough 13 and are finally discharged from the discharge trough 13, thereby achieving rapid separation of solid impurities.

[0038] When the filter hole 4 is clogged, the knocking shaft 9 rotates with the rotation of the motor 14 under the action of the one-way bearing and the belt by reversing the motor 14. When the knocking shaft 9 rotates, the connecting rope 10 on it drives the vibration ball 11 to knock the side wall of the filter cartridge 3. This continuous knocking effectively prevents the filter hole 4 from being clogged. Even if some particles try to accumulate on the filter hole 4, they will be broken up by the vibration ball 11 and discharged smoothly.
